To test how well amylase would break down starch in a very hot temperature, 100ml of water was put into a beaker with a Celsius thermometer and heated until boiling (100 degrees Celsius) using the electric hot plate set on high. When the water was boiling, two test tubes were placed into the hot beaker.One had 2ml of starch in it and the other (the control for all of these experiments) had 2ml of water in it. The test tubes were then allowed to heat in the water-filled beaker. Next, two drops of amylase were added to each of the test tubes.hen the water was boiling, two test tubes were placed into the hot beaker.

When iodine is added to a starch, it adheres to the beta amylose molecules because of their solubility. The starch pushes the iodine into a line in the middle of the amylose coils and creates a transfer of charge between the iodine and starch. This causes a change in the arrangement of electrons and energy level spacings. The new spacings absorb visible light differently and create the deep blue color. Iodine is often used to test foods for starch. Adding iodine to potatoes, dried beans, rice, bread and pasta creates the deep blue reaction to indicate the presence of starch. To perform the test, use a dropper to add one or two drops of iodine to each type of food. Use other foods that do not contain starch, such as apple slices, carrots and sugar, for comparison.
